WINDOW-SHADE HANGER.l

SPECIFICATION forming part of Letters PatentNo. 753,868, dated March 8, 1904.

Application filed May 26, 1903. Serial No. 158,774. (No model.)

.To @ZZ whom t may concern:

Be it known that I, JOHN C. FORSBERG, a citizen of the United States, '-'residing at La Crosse, in the county of La Crosse and State 4of Wisconsin, have invented certain new and useful Improvements in Window-Shade Hangers; and I do hereby declare the following' to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to adjustable window-shade hangers-#to wit, to those -of the general character disclosed in the joint application of John C. Forsberg (myself) and Ole Rogan, Serial No. 139,942, filed January 21, 1903-and has for itsobject to improve the same in the several particulars hereinafter noted.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described, and dened in the claim.

The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a view in elevation looking ata window from the inner side of a building and showing my improved shade-hanger applied thereto. Fig. 2 is a similar view to Fig. 1, but shows the guide-tracks of the hanger applied in a different manner. Fig. 3 is a detail in elevation showing in face view one of the guide-tracks and one of the cooperating roller-supporting heads. Fig. 4 is an edge elevation of the parts shown in Fig. 3, and Fig. 5 is a horizontal section on the line :v5 of Fig. 3. v

The numeral l `indicates the window-frame, and the numeral 2 the window-sash.

The numeral 3 indicates an ordinary window-shade which is mounted on a roller 4 of ordinary construction having at one end a round trunnion 5 and at its other end a flattened trunnion 6, the' latter of whichl is subject to a spring within the roller, which parts are all of ordinary or standard construction.

The numeral 7 indicates channel-like guidetracks, the anges 7 a of which are turned inward to form a sheath having a longitudinal slot between the vinbent flanges. At their lowerends below their inturned flanges 7 the ends thereof. The said upper ends of thev guide-tracks 7 are also providedwith perforations 12, which correspond to the perforations 9 in the lower ends thereof.

The guide-rails 7 are thus adapted to'be s ecured to the fiat inside facing of the window# casing by means of screws 13 passed through the perforations 9 and 12 thereof and screwed into the casings, as Ashown in Fig. l, and .they are also adapted to be secured to the inner edges -of the casing by means of screws 13 passed through the sleeve-like seats 8 and 11 thereof,

as shown in Fig. 2. The trunnions of the roller 4 are seated in the projecting iianges of vertically-adjustable supporting-heads 14, that are vprovided with reversely-bent fiat feet 15 and laterally-bent ears 16. The heads 14 are preferably formed from flat pieces of metal bent to the form illustrated in the drawings, the feet 15 thereof being formed by slitting the inner edge of the plate and bending the slit sections alternately first' in one direction and then in the other, as best shown in Figs. 3 and v5. The feet 15 of the heads 14 work freely in the slotted channel afforded by the back and in turned 1'ianges78b of the guide-track 7 The perforation in one of the heads 14 is made round to fit the round trunnion 5 of the roller 4, while the perforation 17 in the other head 14 is elongated, so as to iit and prevent turning of the flat trunnion 6 of the saidroller, as best shown in Fig. 4. The numeral 18 indicates a draw-cord, which is adapted to be held in various adjustments by a gripping device, shown as consisting of the clamping-plate 19 and a cooperating clamping -lever 2O pivoted thereto. The

clamping-plate 19 is shown as secured to one side of the window-frame, and the depending end of the lever 20 is provided with a perforation through which the lower end of the cord 18 is passed. The upper end of the cord 18 is provided with branch cords 21, the ends or' which are attached one to the ear of each head 14. Both branches 21 work over a guidesheave 10 of the right-hand guide-rail, and the longer of the two branches works also over the guide-sheave 10 of the leftehand rail.

A person wishing to raise or lower the shade bodily first pulls inward on the lower end of the cord 18, so as to release the saine by iinparting a pivotal movement to the lever 20. rlhen, of course, by pulling on the cord or releasing the same the curtain is raised or lowered bodily any desired extent at the will of the operator.

The device described is of extremely small cost, may be very quickly applied in working position, and is easily operated.
